I had the more trusted shop do the drain and refill, they used Subaru fluid without even having to request it. Picked car up that evening and runs great, but when engine gets up to temp, there's a slight odor of tranny fluid/gear oil smell. I looked everywhere and didn't see any drips or spills down in the engine bay, on top of plastic factory 'skidplates' or under the vehicle. Gave it a week and still happens! When the engine is cold, no odor, up near operation temp the odor recurs every time. With engine running (up to operating temp) and hood closed, I did a walk around the odor is most noticeable on left side from between hood/fender, right side not as much.
Called and they said bring it in yesterday morning, got it up to temp and went to see them. They put it on lift, dropped plastic undertrays and nothing, looked all round with a flashlight, nothing....even took me back and let me look around with them. I've changed many manual and automatic transmissions fluids myself and never encountered this unless there was a drip, spill or leak. They did show me the CVT vent hose on right side of the transmission, just a little rubber hose with standard 180* loop at the top to help keep debris out, seems like they would have broght this vent line up high and used a tiny clamp on it to better keep junk out! Anyways, the odor is still there, any ideas?
